Biliary atresia (BA) should be suspected when a triad of findings is observed in the neonate or young infant.


Clinical triad for biliary atresia:

(1) jaundice with conjugated hyperbilirubinemia that persists after the first 2 weeks of life

(2) white stools (acholic) and dark urine

(3) hepatomegaly


Complications that may occur if the diagnosis is not made early:

(1) intracranial hemorrhage or other bleeding secondary to vitamin K deficiency (hemorrhagic disease of the newborn)

(2) infantile cirrhosis
